How Many Under-tightened Diesel Intake Clamps

On the intake of the Diesel, there are 5 hose clamps holding together the various pieces between the air filter and the entrance to the turbo. These are the type that use a flat head screw to tighten them around the tube. When I checked mine tonight while changing my air filters, I discovered that 3 of the 5 were under-tightened--two of them so loose I could turn the screws by hand without a screwdriver. As un-metered air entering the intake has been proposed as a contributing factor to the sensor failures that some of us have experienced, this is something we should all probably check, along with visually inspecting for areas that could be drawing air. I would like as many Diesel owners as possible to check their hose clamps and report in the poll above how many were under-tightened. If you had any under-tightened clamps, post the age and mileage of your vehicle below. (2 years, 46,000 miles for me.

All are tight on my Cruze, there is also a smaller tube coming off the intake going to the head with 2 spring clamps. I have the Australian Cruze so this may be different on the US Cruze.

I found 3 in total, 2 that were loose enough to possibly let unmetered/unfiltered air in, and one that needed to be snugged up. Its definitely worth the time to do a quick check during oil changes.

2014 CTD with 14,000 miles when I checked them.

I finally went down and checked mine, and had 3 that were slightly loose. The tow on the left, and the one on the far right by the turbo. I don't think they were loose enough to let air in, but I was able to get between 1/2 and about 3/4 turn on them to snug them up.

So anyway, I tried to go into the poll and update my answers and somehow managed to lose one of the options. Sorry everybody! I ended up removing the option that had zero votes.

I just checked mine and all five were at least 1/2 turn loose and three were 1 and 1/2 turns loose. I voted three of five because the two 1/2 s were somewhat snug.

Sounds like my wife, she can't open her petrol cap either.
Thats why my girlfriend drives my jeep zj. every single thing that can take a fluid is color coated so that it follows the legend on the radiator frame. red cap on the stick is ATF, green cap is rad overflow, yellow is motor oil and so forth. they literally wife proofed the jeep.... yah never mind

I have a feeling this post/poll will save more than a few people from check engine lights that would have otherwise happened and potentially turned into nightmares.

None that I know of but then again I'm a horrible mechanic. 20000 km and only the dealer has lifted the hood. You'd think being a mechanic I'd want to check out my own car but no as long as I don't have to pay for service I reefuse to go near it!!!

That's me!!! I'm an electrician but for 6 years I worked at my dad's shop. I open the hood only to top up windshield wash and sometimes just to see what it looks like under there.

I just take a black sharpie and mark everything. Battery, radiator, radiator overflow, windshield washer fluid , oil, brake fluid etc. my dad taught me all about cars, but I don't expect my kids to know unless I teach them. Most people just want to put gas/diesel In their Cruze and just go........
